Our take on the Milwaukee 4-1/2 in. 11 Amp Corded Angle Grinder 6142-30

The Milwaukee 6142-30 is a corded 4-1/2 in. angle grinder with an 11 amp motor rated at 1,400 maximum watts of output. Its pitch is durability and control: a slim 2 in. smaller grip circumference than rivals, a lock-on paddle switch, and electronic protections including overload protection, an electronic clutch, line lock-out and soft start. It is built for industrial and heavy shop use, where it competes with other 11 amp grinders on motor protection and tool-free wheel changes rather than on portability.

Questions and answers

Is the 6142-30 good for heavy daily grinding?
Yes. Its 11 amp, 1,400 MWO motor and electronic overload protection are aimed at industrial, all-day use. It is corded, so it stays on full power as long as it is plugged in.
How does it differ from Milwaukee's other 4-1/2 in. grinders?
This is the 11 amp lock-on paddle model. Other versions use a trigger or a slide switch, and lower-amp models trade some power for less weight.
Does it have a brake or variable speed?
No. It has soft start, an electronic clutch and line lock-out, but no speed dial and no fast-braking motor.
What wheels does it take?
It uses 4-1/2 in. wheels with a 5/8-11 spindle, and the tool-free design lets you mount hubbed wheels without a wrench.
Is the guard adjustable without tools?
Yes. The burst-resistant guard adjusts and installs tool-free.
Who should not buy it?
Anyone who needs a cordless tool for ladder or overhead work, or who prefers a dead-man trigger, should look at a battery grinder or a trigger model.
